I have been obsessed with these black framed windows and doors for years. When we were house hunting, i had searched for a supplier, and quoted up a wall of them before we found where to put them. Of course the house we bought had a wall of collapsible white framed doors, that unfortunately worked too well to justify replacing.
I'm still storing these images up for use sometime in the future. In Australia, these windows can be sourced through Skyrange.
